Senior BJP leader Mukul Roy said this is how a federal structure should work. Despite welcoming the meeting, Mukul Roy went on to take a dig at the West Bengal chief minister.

"If CM has sought time to meet PM (Modi), he should definitely meet. Similarly, if CM has been called by the PM or HM, she (Mamata Banerjee) should also oblige," Roy said.

He said, "When Mamata was called to Delhi so many times by the PM and the HM, she didn't bother to turn up. Now she's inviting PM, but we welcome this change."

Commenting on the National Register of Citizens, Mukul Roy said it is not just limited to one state but for the entire country.

"Mamata should decide if she wants to protest against NRC or support NRC," he added.

Earlier in the day, Mamata Banerjee met with Prime Minister Narendra Modi at his residence in New Delhi. Banerjee, who gifted the prime minister kurta and sweets, said the meeting was non-political and fruitful.

She also invited PM Modi to the state for flagging off the coal field project in Birbhum.

"I have urged PM Modi to come and inaugurate world's second-largest coal block which is coming to West Bengal," Mamata Banerjee said.

This was the first time Mamata Banerjee met with PM Modi after he came to power for a second term.

"It was only a chair to chair meeting, not a political meeting. If Amit Shah can give me time, I would want to meet him once tomorrow for courtesy," Mamata Banerjee said.

Meanwhile, as the city of Kolkata gets ready to celebrate Durga Puja, it has come to light that JP Nadda will organise a mass torpon - an offering made to pay homage to ancestors - at Babu Ghat on the day of Mahalaya.

Nadda will pay homage to the political workers who lost their lives in West Bengal's political tension.

JP Nadda will be reaching Kolkata on September 28 to attend an organisational meeting and to address an event on Abrogation of Article 370. Amit Shah is scheduled to visit Kolkata October 1 to inaugurate 4 Durga Pujo pandals in Kolkata.
